The standard electric power on the NIR laser even now has the possible to get improved to tens of watts including 70 W [26] When the double-pass configuration may very well be utilized with the Yb:YAG SCF amplifier stage. As a result, In case the conversion performance of 31% from NIR to DUV may be nevertheless managed at this larger power affliction, the average output electrical power of your DUV laser at 258 nm might be in excess of twenty W, which might be a extraordinary energy stage for the DUV laser and result in the unanticipated DUV laser machining final results. Additionally, for prime-electricity DUV laser, the UV problems with the nonlinear crystal, such as the windows for CLBO crystal as well as the mirrors, is yet another critical parameter for lasting and steady operation.
Alternatively, the beam quality of the higher electric power DUV laser would become even worse as a result of extra really serious thermal and nonlinear effects. That's why, the frequency conversion procedures need to be cautiously intended to mitigate the aforementioned outcomes. Consequently, a superior-power DUV laser in the FHG of one μm with a great beam quality could possibly be received and can be useful for acquiring the shorter wavelength DUV lasers for instance 193 nm by SFG.
Both of those the 1040 nm and 1078 nm laser originate from a person twin-wavelength Yb-doped fiber laser. Each individual laser is amplified by stages of fiber amplifier and Yb-doped materials amplifier, respectively.

Soon after payment, you might get an e-mail with Directions along with a url to down load the acquired paper.
Furthermore, combining the good-state laser with other nonlinear course of action such as stimulated Raman scattering, NIR lasers may very well be reached at new wavelengths with higher power and substantial beam quality, which was analyzed through the evidence-of-principle experiment. This Raman laser scheme delivers a completely new path to the high-electricity DUV laser, especially with the wavelength of 193 nm.

The development on the 193-nm laser was shown by levels of SFG. As a way to scale the DUV laser ability correctly, a fresh principle of your 193-nm DUV laser generation is presented depending on click here the diamond Raman laser.
